I don't know if anybody already pointed this out, but in the second time jump you can see Peter is wearing a wedding ring and then it's gone. Is it intentional or not?

It could be a possibility that Peter was not jumping in time but jumping between realities? Im sure that in the original fringe-verse both here and over-there were out of sync time-wise meaning that Peter was jumping through forward and behind realities ?
